ENERGYEFFECTIVE STRUCTURES OF HAULING ELECTRIC DRIVES ARE IN BRAKE MODES

Abstract:

The questions of transformation of electric energy in the hauling electromechanics of direct-current were considered in the article. The necessity of modernisation of structures of hauling electromechanics of direct-current was reasonable. Two the variants of circuit technology decisions of effective transformation of electric energy in the hauling electromechanics of direct-current were worked out.

Transformer with two levels of adjusting of tension and consistently-parallel connection of hauling electric engines it is the first variant. Main dignity of chart it is minimization of total losses in an electromechanic, reduction of pulsation losses, due to a decline twice of amplitude of pulsations of tension and current in hauling engines. Currents of engines in hauling and in a brake modes will be identical and engines create identical hauling and brake moments. A chart will not allow to distribute loading between engines and hauling and brake possibilities of electric locomotive not to realize fully at loading near to maximal.
